The Merino Blend Run+ Ultralight Micro are breathable and naturally odour-resistant socks for all-round running performance. The ultra-lightweight design is anatomically sculpted for premium fit and comfort, with key support zones in the Achilles and instep to keep the sock in place. Reinforcements in the heel and toe help enhance durability, while the seamless toe reduces bulk. These socks also feature reflective details at the cuff. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino wool is an annually renewable fibre that naturally resists odours, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
